Sole Cloud Flying Cave

Cui Heng was transmigrated to another world and the system told him that the new world he was in was a high-grade Xianxia world.
It was a world where Celestial Kings soared the sky and terrifying monsters ruled the lands. The strong would destroy a planet if their mood was bad and Cui Heng trembled in fear when he learned of how scary the new world was.
Thankfully, the system had granted him the protection that last for 300 years. As long as he remained in the safety zone, he would not receive any damage.
With his safety secured, he began his cultivation training for the next 300 years.
Throughout the years as he trained, some people entered his safety zone by mistake.
There was a peasant who was once a monk and a beggar. Despite that, he still had the dream of bringing peace to the land and saving the lives of millions.
There was a noble who was once called the once-in-a-million-year genius. Yet, luck wasn't at his side and his talent fell and was laughed at by others for years.
There was a princess whose only wish was to find her older brother. She could've become a celestial but decided to remain in the human realm to wait for her brother's return.
There was a weak lady who was plagued with illness from birth but had the goal of adventuring and helping the poor and weak.
...
Cui Heng befriended these people and even gave them a few pointers before they left.
300 years later, when the protection period had ended, he had finally mastered the Golden Core. Even then, he was still reluctant to go to the outside world.
But when he did, he realized that the world was merely a world of Wuxia.

Realizing This Is A Wuxia World After Cultivating For 300 Years

Cui Heng frowned when he heard this name.

Was he talking about Zhou Juntian?

Back in the Silver Disc Star Sea, a group of "Outer World" experts had addressed Zhou Juntian like this.

At this moment, Cui Heng was really surprised to hear the name Venerate Juntian from the son of the Human Monarch.

It had been a long time since he heard any news about Zhou Juntian.

After all, with Zhou Juntian's situation, it was almost impossible for him to come into contact with experts in the Upper Three Dao Realms and above.

Logically speaking, Zhou Juntian's strength should be equivalent to the natural-born Supreme Venerate of the Daozhou Star's Heavenly Void World, the Holy Mother of White Lotus of the Three Higher Heavens, and the Lord of the Heavenly Court of the Heaven Realm.

He should not be capable of growing endlessly stronger like the Immortal supporting characters of legends.
